That's awesome! I'm just learning rust and I'm really enjoying it, though it was more challenging getting into the right mindset after working on GCed languages for most of the last 4-5 years. Certainly wrestled with the ownership system for a while but it's all making a lot more sense now, and I'd much rather have the compiler telling me about these problems than incorrectly dereferencing memory in C code. How long have you worked on only this project? |

It's hard to quantify how much time _this_ project took, since when I started a year ago I knew nothing about Doom or Rust. If I started writing it now from scratch, I could probably hammer it out in a working week. A better programmer could probably do it in a weekend. It's neither very big nor very hard.
But that's not how programming works, is it? In fairness, you'd need to count some of the time I spent working on a lot of other random Rust side projects and reading blog posts over the last year, while only spending a couple of hours ever other week or so on rust-doom.

I think my background in modern C++ helped me a lot with this, since the "one owner per thing, move semantics" model is how you're supposed to write C++ too.
That said, figuring out the cleanest design is not easy and I'm still wrestling with it today. The code was an absolute mess last year and now it's better, but still needs plenty of work: just yesterday I decoupled WAD parsing from the rest of the code properly (https://github.com/cristicbz/rust-doom/pull/53).
I'm still learning a lot a year after dedicating all my free-time programming to Rust.
